Research

Assess the predictive value of quantitative electroencephalography (qEEG) and of brain imaging (Single-Photon Emission Computerized Tomography (SPECT)) measured during REM sleep compared to other markers in patients with mild cognitive impairment, such as qEEG and SPECT during wakefulness, specific neuropsychological tests and brain morphometry, in order to identify subjects who will convert to Alzheimer’s disease at a three-year follow-up.Collaborators: Isabelle Rouleau, Jean-François Gagnon, Nadia Gosselin, Jean-Paul Soucy, Serge Gauthier, Marie-Jeanne Kergoat

Somnambulism:

Study the slow-wave sleep processes during normal sleep and after sleep deprivation in sleepwalkers and controls using quantitative EEG and brain imaging (single photon emission computed tomography (SPECT)), and use waking EEG recordings, vigilance tasks and SPECT imaging to investigate electrophysiological and neurobiological processes during normal wakefulness and following sleep deprivation in sleepwalkers and controls.Collaborators: Antonio Zadra, Jean-Paul Soucy

REM behavior disorder:

Evaluate the evolution of the neurological (motor and sensory) and cognitive (memory, attention, language, visuospatial perception) functions, that of the brain electrical activity during wakefulness and during sleep and that of the brain imaging of patients diagnosed with REM sleep behavior disorder. The purpose of the study is to verify whether some of these tests can predict the short-term occurrence of a neurodegenerative disease and to study how these markers progress in preclinical stages.Collaborators: Jean-François Gagnon, Ron Postuma, Jean-Paul Soucy

Longitudinal study of sleep in children and adolescents:

Study in a large cohort of children in Quebec the evolution of sleeping patterns from birth to adolescence, prevalence of and factors associated with dyssomnias and parasomnias, and the consequences of insufficient nighttime sleep duration in early childhood on various child development domains (cognitive performance, language, behavior of overweight and obesity hyperactive-impulsive, etc.).Collaborators: Richard Tremblay, Michel Boivin, Frank Vitaro
